A method for automatically recognizing an end of a welding member using welding current data per rotating positions of a welding torch is provided to automatically recognize the end of the welding member when a welding current difference value between a fore region and a rear region is a critical welding current value or more by detecting the welding current data per the rotating positions of the welding torch. A method for automatically recognizing an end of a welding member using welding current data per rotating positions of a welding torch comprises: a step(S501) of performing rotating arc welding by controlling height of the welding torch and tracking of a welding line; a step(S503) of being feedback and detecting the welding current data per the rotating positions of the welding torch when performing the rotating arc welding; a step(S505) of comparing a critical welding current value with a welding current difference value between a fore region and a rear region based on a proceeding direction of the welding torch using the detected welding current data per the rotating positions of the welding torch; a step(S507) of recognizing the fore region as the end of the welding member when the welding current difference value between the fore region and the rear region is greater than the critical welding current value; and a step(S509) of performing end rotating welding using the recognized end of the welding member.
